Step-by-step explanation!
Hope this helps everyone :)
1) x=6, y=3
2) no solution
Divide by the coefficient of x.
x = 27/47
Set up a ratio of known to unknown:
Let X = the amount of gas needed for 500 miles:
220/12 = 500/x
Cross multiply:
220x = 6000
Divide both sides by 220:
X = 6000 / 220
x = 27.27 gallons (round answer as needed).
